This function ensures that the network devices specified in the configuration are registered and handled by UDEV. Sometimes, the initialization of network devices might take a significant amount of time, and the sriov-config systemd service may start before the devices are fully processed, leading to failure.

Is this supposed to run in the host chroot? I tried running it in the config-daemon pod:
[root@cnfdr22 /]# udevadm settle -t 10
Running in chroot, ignoring request.

Currently this function will never run inside the daemon Pod. The function is executed by the sriov-config and sriov-config-post-networking systemd services on boot. When running as a part of systemd service the functions have direct access to the host's tools and there is no need to use chroot

Got it, I wrongly thought the systemd service was running the config-daemon via podman run ... .
thanks for explaining
